Phase-folded X-shooter (blue) and Hermes et al. (2017a, green) radial velocity values. The data were phased with period from radial velocity variations. The inlet shows the periodogram of the radial velocity values as a function of the relative period difference ΔP/P × 10⁴, where P is the orbital period derived from the radial velocity variations. The arrow indicates the period derived from the photometry.
